16 Surprising Sources of Protein

Protein does more than just build strong muscles. It also strengthens bones, increases satiety, protects against heart disease, and helps support a healthy immune system. We also know that consuming plenty of protein is an essential component of achieving and maintaining a healthy weight. When most people think about protein, foods like chicken, beef, pork, and eggs usually come to mind. But there are several hidden protein treasures that can help you meet your needs while also helping you cut back on your meat intake.

Beans

Beans are well-known for being high in fiber, but did you know they are also high in protein? Beans are a wonderful source of protein, ranging from 10-18 grams per cup cooked, depending on the type. They're also versatile and economical. Dried beans are very inexpensive and can be incorporated into a variety to dishes. Diets that include beans may reduce your risk of heart disease and certain cancers. Another bean bonus: A recent study found that people who eat beans weighed on average 7 pounds less and had smaller waists than those who didn't eat beans. To reduce some unpleasant side effects, rinse beans in water to reduce their gas-producing effect.

Quinoa

Another surprising source of high-quality protein is quinoa. Quinoa, a seed that's commonly thought of as a grain, was originally cultivated by the Incas in South America but is gaining popularity worldwide. A quarter-cup of cooked quinoa provides 5 grams of protein. It is especially rich in the amino acid lysine, which is important for tissue growth and repair. Quinoa works well in soups and salads and can easily serve as a substitute for rice in most recipes.

Soybeans

Soybeans are the only vegetables that are a complete protein, meaning it contains all nine of the essential amino acids--amino acids that our bodies can not make and must be obtained from food. In fact, soybeans produce more than two times as much protein per acre of land than any other crop of vegetable or grain. Soybeans are used in a multitude of foods, including soy milk, tofu, tempeh (fermented soybeans), soy cheese, soy yogurt, soy nuts, edamame (green, immature soybeans), mature yellow soybeans, miso (a thick paste made from fermented soybeans and barley or rice malt--used in Japanese cooking to make soups or sauces), textured vegetable protein ('TVP'--used as a meat alternative), and others. The protein content of soy foods varies, ranging from about 25 grams for a ½-cup serving of TVP to 4 grams for a 2 Tbsp serving of miso paste.

Nuts and Seeds

Nuts and seeds are also a meat-free protein source. A one ounce serving of most nuts and seeds provide about 6-9 grams of protein.

Other lesser known protein sources include:

• Cottage cheese (14 g per ½-cup / 4 oz. serving)
• Dried spirulina seaweed (8.6 g per 1 cup serving)
• Bagels (7.2 g per small bagel, 3" diameter)
• Oatmeal (6 g per 1 cup cooked)
